Airbus has said that the equivalent of almost two full months of A320 production is now waiting for engines from P&W.
The airline is running out of space to store the aircraft and is anxious that the backlog doesn’t get any worse.
The financial consequences are also significant with 100 incomplete aircraft worth some $5.2 billion, unpaid for.
The problem won’t even stop when the engines become available, as the aircraft have to have them installed and be flight tested prior to delivery, a process that can take up to two-four weeks per aircraft.
Some of the latest aircraft in the holding zone may not be delivered for as long as 9 months.
